Faerie Wars

I need to do a LOT more research on folklaw before I will be able to build this into a story. I read a little about the Fae when I was younger and got the impression of something far darker than Tinkerbelle. The fledgeling idea is that there is was between the Faerie tribes going on around us all the time, that some of them care if we get caught in the cross fire and some of them don’t. Of course there would need to be a cross over character to act as a gateway to the Faerie world, a human through whose eyes we see the action, and a charter or even that pulls them over. I have an idae of where I want to begin but no idea where I want to go from there. Plenty of scope to play though.
